Abstract
In a case in which a vehicle is to be decelerated through a regenerative braking force of rear wheels, when the vehicle is turned, a vehicle control device reduces the regenerative braking force of the rear wheels from a regenerative braking force at a time when the vehicle is not turned, and increases a friction braking force of four wheels by an amount corresponding to the regenerative braking force of the rear wheel to be reduced.
